Disclosed is anhydrous cosmetic compositions comprising: (a) a heat generating agent which generates a heat by mixing with water; (b) a phase changing agent; and (c) an inert carrier;wherein the phase changing agent has a melting point of from about 30oC to about 70 ~C and are dispersed in the inert carrier. The composition of the present invention warms by mixing with water, and provides enhanced efficacy preventing the compositions from reaching a higher temperature than that being expected, and also provides prolonged warming from the compositions.

L'invention porte sur des compositions cosmétiques anhydres contenant : (a) un agent générateur de chaleur qui génère de la chaleur en se mélangeant avec de l'eau ; (b) un agent de changement de phase ; et (c) un excipient inerte, l'agent de changement de phase ayant une température de fusion de l'ordre d'environ 30 à 70·C et est réparti dans l'excipient inerte. Cette composition selon l'invention se réchauffe en se mélangeant avec de l'eau et présente une meilleure efficacité en empêchant les compositions d'atteindre un degré de température plus élevé que prévu. Elle garantie également un réchauffement prolongé des compositions.
